To all whom it may concern:

Be it known that I, ROBERT F'.- BowER, citizen of the United States,residing at Dayton, in the county of Montgomery and State' Thisinvention relates to improvements in roller or anti-friction bearings,and comprises certain structural features and advantages hereinaftermore fully described.

The objects of the inje'ntion are several, principali r among which isto provide a per-4 feet end-thrust roller bearing in which the endthrust from either side is substantially met and taken. And further, toprovide a more rollersrnay be removed without disturbing the otherrollers or disconnecting the parts of the supporting traine or cage.-

Preceding' a more detailed description of the invention, reference ismade to the accompanying drawings, of which-"- Figure 1, is alongitudinalsectional view of an automobile hub with spindle therein, aidin which my in double series. Fig. 2, 'is' an end `'."iewof tht bearingremoved, part of one of the suppol ting rings being-.broken away andsome the rollers.

of the rollers a pearlng in section.v FiguS is a detail 1.iew oftheouter su porting ring for Fig. 4, is an e arged detail sec- -tionali'iew of one of the rollers position. Fig. 5, is a detail view inperspective, of the supporting frame or cage.

n a detailed description of the invention, similar reference 'characters.indicate corresponding parts. For the purposes of describing andillustrating my im roved bearing, I showin the drawings a we l-knownform of automobile hub A. and an automobile spindle or axle B with a cap nut C inclosing the end ofthe Aspindle in a well-known manner.

In this gure of the drawings, there are illustrated two sets of bearingsand. endet-ail `descri tion of one is a description of the other, and Yde sire further to state lthat the bearing is not" alone confined toautomobile spindles, but

which one or impro-.ed bearing is placed;

may be utilized-wherever a bearing of this type may be used.

D designates a series of rollers each of which has an enlargement E withinner and l outer tapering surfaces e.

The' ends of these rollers are provided with j ournals f and g theformer being smaller than the latter, and the larger journals g being onthe ends ofthe rollers on which the enlargements E are located. r[heseenlargements E are for the purpose of taking and meeting the end thrustsfrom either side. The rollers so formedare supportedin a circle in thecageshown in Fig. 5

which is made up of rings F and G which are united by a -series of cross'rodsl Hl The VringGf is provided'with a suitable number of slots ientending inwardly a suitable distance from the peripheryof the ring.'These slots i are of sufficient size to receive the larger journals g ofthe rollers; 'Ihe ring F has a series of smaller openings a in alinement'with the larger openings 'i in the ring G. The openings a are somewhatlarger in diameter than the smaller j ournals f ofthe rollers as is moreclearly shown in Fig. 3, in order-that each'individual roller may beremoved from the cage without detaching any part thereof. In assemblingthe rollers in this supporting frame or cage, .the smaller journals areinsertedin said openings d' and the rollers are dropped into position bythe larger journals g entering the openings i.

Coming now to an important feature of my improved roller bearing Vwhichcoperates withthe double tapered enlargements E, of the rollers, H and ldesignate, respectively,

inner and outer bearing sleeves whichinclose the rollers 'D and which inconjunction with said rollers, form the anti-friction bearing. 'I heinner ends of these sleeves have tapering surfaces m and n which` matchthe tapering surface e on one side of the roller ments and engage said`tapering surfaces snugly.

J is an end-thrust ring in alinementl with the'outer bearing rin I andhaving a tape red surface b matching tglie tapered surface e on theroller enlargements and in engagement with said surface. V

It will be seen that the enlargements of the rollers are inclosed on theouter side of. the bearin between these two tapered surfaces n and andthat such points of contacter(- tendthroughout the length or width ofsaid .L

tapered surfaces and thus provide a subs tial engagement between theroller enlargeenlarge-V ments and the outer bearing ring I and the, endthrust ring J. The same is true of the` tapering surface m on the end ofthe inner bearing sleeve H, such tapering surface engaging the length orWidth of the tapering surface of the enlai gements on the inside of ,therollers. The end thrust ring J is held by a shoulder c on the interiorof the hub, while the inner bearing sleeve His held by a collar clsurrounding the axle or spindle B.

Fromthe foregoing description, it Will be apparent that a mostsubstantial means is here provided for taking the end thrust from eitherside of the bearing, and owing to the matching and engaging taperedsurfaces c m n b, the Wear will be uniform throughout the engagingsurfaces.

As before stated, Fig.- 1 illustrates two sets of bearings inconnectionwith an automobileI spindle. From this illustration oi such anapplication of my improved bearing, it will be seen that an inward endthrust will be eX- ertedupon the inner sleeve H and the outer Y dle. AAnoutward end thrust will be transmitted in a similar manner and will beborne by the collar L on the outer end of the spin- While l have shownand described the cage with the inner -ring G provided with the largerournal openings t, it will be understood t at the larger openings may bemade in the inner ring Without extending them to extended to theeriphery of said ring in ory der that the sma er roller journals f maybe dropped into position in said outer ring after the larger rollerjournals g have been inserted\ in the openings in the inner ring. y

Having described my invention, I claim: ln a bearing of the typespeeied,a series of rollers having enlargements with oppositely-disposed taperedsurfaces, and {ournals projecting Jfrom the ends of said ro 1ers,

a cage comprising two united yringsvvith suitable openings therein, theopenings in one of said rings being ada ted to receive the journals onone end of t e rollers by a longitudinal movement off each roller, andthe openings on the other of said rings beingada ted to receive thejournals on the other end o the rollers by a lateral movement of therollers, an inner bearing sleeve within the cage and engaging the innersides of the rollers, said inner bearing sleeve having its inner endtapered and engaging the tapered surfaces on the outer sides of theroller enlargements,

an outerbearing sleeve for said rollers, the inner end of which istapered and engages the outer taperedsurfaces of the roller enlarge-vments, and an end-thrust ring having a ta-l ered surface engaging theinner tapered suraces off the roller enlargements, said endthrust ringbeing in alinement with the outer bearing ring.

In testimony whereof I affix my signature,

in presence of two witnesses.
